Quality assurance in human molecular genetics testing: status and recommendations

Area of Science:

• Human molecular genetics
• Quality assurance in genetic testing
• Public health

Background:

• The rapid advancement of genetic testing technology and the completion of the International Human Genome Project have outpaced the development of quality control methods.
• High-quality genetic testing is essential for public health.
• The Centers for Disease Control and Prevention (CDC) initiated efforts to enhance quality assurance in human molecular genetics testing.

Framework:

• Expert consensus was reached through three panel meetings involving 28 specialists in molecular genetics testing and quality assurance.
• Recommendations were informed by expert opinion, laboratory visits, and literature reviews.
• The project addressed needs identified in 1997 reports from the National Institutes of Health, Department of Energy, and the Clinical Laboratory Improvement Advisory Committee.

Implementation:

• A participatory visioning approach and a modified nominal group process were used to identify research and development needs.
• Fifteen panelists contributed to developing consensus recommendations.

Implications:

• Five core recommendations were established: research for quality assurance positive samples, enhanced performance evaluation programs, support for laboratory consortia, creation of a laboratory-focused database, and investment in molecular genetics training programs.
• These recommendations aim to improve the quality and reliability of human molecular genetics testing.
• Implementing these measures will support the responsible expansion of genetic testing applications.
